Well, I'm interested.

Don't get me wrong. I like my N900, mainly because it is the best open, (mostly open, anyway), Linux-based, hackable phone/computer on the market today.

However, I'm eager to see how it all could be further improved. More openness (less proprietary software equals more hack-ability and changeability) is always welcomed. Better hardware (longer battery life, faster, more capabilities, sensors, multi-touch, magnetometer, etc) is also very much appreciated.

I'm not saying Aava, N9, or any of those phones have it all, but I appreciate any effort of improving the current state of the art FOSS phone/tablet/devices support.
